ARMIORED PNEUJATEC DSK WHEEL Application filed January 9, 1922.

T 0 all whom t may concern.'

Be it known that we, WILLiAM Gr. HAW- niNs and VIVIAN C. Briooneooo, citizens of the United States, and residents of the city of Harvey, in the county of Cook and State of illinois, have invented certain new and useful Improvements in 'Armored Pneumatie Disk Wheels, and we hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention covers an improved type of an armored pneumatic disk wheel of comparatively light weight having concentric pneumatic tires the felloe of the outer tire resting on the inner tire and connected with the inner tire housing disks by driving mechanisms adapted to permit a drive from the wheel to be imparted to the outer tire.

It is an object of this invention to provide a simplified form 0f a double tired armored wheel wherein pivot-ally connected push mechanisms connect the tire supports.

t is also an object ofthe invention to construct an armored wheel having intel` fitting tire supporting sections connected to one-another atintervals by pivoted mem-A bers adapted to cause compression of resilient members carried by one of said tire supporting sections whereby a pushing force is exerted t0 cause rotation of said tire supporting section by the other of said sections.

It is a further object of this invention to provide a light weight armored wheel wherein van outer tire is removably locked on an outer felloe which slidably interiits with an inner tire carrier to be driven thereby through pivoted push mechanisms.

It is an important object of this invention to provide a vehicle ywheel having an outer tire carrying felloe resiliently supported on an inner pneumatic tire the housing of which is rigidly secured to a hub supported disk and is connected with said felloe by improved push 'mechanisms engaging resilient pads carried by the felloe. p

Other and further-important objects vof this invention will be apparent from the disclosures in the specification and drawings.

The inventionY (in a preferred form) is illustrated in the drawings and hereinafter more fully described. A

Serial No. 527,306.

On the'drawings:

Figure 1 is a side elevation of a vehicle wheel embodying the principles of this invention.

Figure 2 is an enlarged section taken on line 2-2 of Figure 1.

Figure 3 is a fragmentary sectional view .taken en line 3 3 ofFigure 2 with parts in elevation.

Figure 4 is an enlarged fragmentary detail `section taken on lines 4--4 of Figure 3.

Figure 5 is a fragmentary detail section taken on line 5-5 of Figure 4.

Figure 6 is an enlarged detail section taken on line 6-6 of Figure 1 illustrating the outer tire lock mechanism.

As shown on the drawings:

"The armored pneumatic disk wheel comprises a hub 1 provided with a hub cap 2. integrally formed on the hub l are spaced peripheral flanges 3 having apertures therein through which bolts 4 project for the purpose of rigidly securing to said hub a ring disk 5 made of wood or other suitable light weight material. The ring disk 5 is offset at 6 and has a plurality 0f recesses or pockets 7 formed in the outer peripheral concave surface thereof.

Engaged around the ring disk 5 is an inner pneumatic' tube or tire 8 having integrally formed on the inner periphery thereof lugs 0r projections 9 adapted to seat in the recesses 7 of the ring disk to prevent creeping of the tire 8 with .respect to the ring disk 5. The inner tire 8 is provided with an air valve l0 and with a plurality of solid rubber shoes or blocks 11 integrally formed at spaced intervals on the outer peripheral surface of said tire. R-igidly secured by means of bolts 12 to the opposite sides of the outer margin of the ring disk 5 are the inner margins of two side plates or disks 13 curved at 14 to oifer a housing for enclosing the tire 8. @ne of the side plates 13 is provided with an opening 15 through which the valve 1() projects. Each side plate 13 is provided with an integral projecting channel 16 near the'outer periphery thereof. Seated in each channel 16 are 'crimp springs 17 and strips of packing 18 Vflanges '20 andVK 21 which project inwardly betweenthe side plates 13 and the packing strips 18 thereof. Projecting outwardly at Vright#angles'from' the felloe side flange 21 Where it Vjoins the-rim 19 isa rim flange 22 having aplurality of openings therein Yat equally spaced lintervals and communicating with openings 23in the rim 1 9v and with openings '241 inthe felloe flange 21.

Integrally formed at one edge of theV rimV 19Vwherc it joins the flange 2O is an outwardly directed curved rim flange. 25 for retaining an outer pneumatic tire 26 in place n upon the felloe rim 19. A tire retaining ring 27 is slidably engaged around the felloe flange 22and is adapted vto coact with the rimflange 2 5 to hold the outer tire 26 secured in place on the rim 19. For holding the ring 27 locked in place on the felloe a plurality of lock mechanisms are provided at spaced intervals within the felloe. As illustrated'in Figure Z6 each ring lock nieclr anism A conriprises a .housing or casing 28 secured tothe rim 19 and the rim fla-nge 21 at the openings 23 and 24h Positioned within'the lock casing 2S is a spring 29 one end f of which is attached to the inner end of a latch har 30y deflected at 31' and 32 to p ermit the head 33 of the latch'ba-r to project through the felloeopenings 23 and2i1 and through the opening in the rim flange 22 in which. position the latch head 33 engages tothe. outside of the ring 27 to hold the 1 same in place. e 'Rlgidly secured at spaced intervals to the felloe flanges -20 andl 21 are a plurality of caps or heads 34 which seat over the shoes or blocks 11 ofthe inner tire thereby affording 1a resilient support or cushion forV the. outer tire felloe. VEach of the felloe Yflanges v2O and 21 are cutaway atV spaced intervals to afford notches or openings 35.

Asillustrated in Figure 1, one of the side j vtire 26 a plurality of drivemechanisms areV rovided at spaced intervals'betwcen theY outer tire felloevand the wheel'side platesY V13'.v AEach, drive mechanism embraces a casplatesi113-is 'provided withV an opening 36 to, permit access to the air valve 37 of the outer, tire 26. Pivoted at `the point 38 on theside plate 13 is a liap or shutter 39 for 'closing the opening 36.

For the p urpose of causing a driveto be imparted from the wheel hubV to the outer ing tlrigidlysecured to the inner peripheral surface of the outer tire. r1in19 andhava' pair ofzoppositely disposed brackets or arms, 41.: The casing 40 isprovided with an opening 42 through which theshort arm',

The Vfelloe flanges 20 and .21 telescope into the wheel disk sectionbetween the side plates 13and Vact to cause compression of' thejinner pneui matic'tire 8 which serves'as acushion for resiliently supporting the weight of the ve hicle.
